For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0030] First embodiment:
[0031] Please refer to Figures 1 to 8 As shown, the embodiment of the present utility model provides an electric toothbrush tail plug structure, comprising:
[0032] The tail cover body 1 is formed on the electric toothbrush body or connected to the electric toothbrush body. The tail cover body 1 has a hole 11 formed on the end surface, and a space 12 for accommodating a USB slot is formed inside the hole 11.
[0033] A USB plug cover 2 is provided at the hole 11 and is used to partially detachably close the hole 11; and
[0034] The plug cover fixing member 3 is fixed to the tail cover body 1 through a mounting structure to prevent the USB plug cover 2 from completely detaching from the hole body 11. The mounting structure includes a plug structure, a threaded structure or a snap-fit structure.
[0035] Specifically, the tail cap body 1 includes a cavity 13 formed inwardly on the end surface, and an opening is formed on the end surface of the tail cap body 1 to communicate with the cavity 13. The lower end of the cavity can be closed or open. In this embodiment, the cavity 1 is a closed structure formed in a hollow protrusion 19 below the tail cap body 1.
[0036] The USB plug cover 2 includes a plug body 23 corresponding to the shape of the hole body 11, and also includes a tail for extending into the cavity 13. The USB plug cover 2 is also formed with a card block 22 on the tail, and the plug cover fixing member 3 is fixed at the opening to prevent the card block 22 from detaching from the cavity 13.
[0037] As a specific example of the plug-in structure, the plug-in structure includes a slot 14 . The tail cover body 1 radially extends at the opening to form the slot 14 . The plug cover fixing member 3 is fixed to the tail cover body 1 through the slot 14 .
[0038] Furthermore, the tail cover body 1 forms a first table 15 and a second table 16 from the outside to the inside at the end surface, and the slot 14 includes an upper slot 141 provided on the first table 15, and a lower slot 142 provided on the second table 16. The width of the upper slot 141 is smaller than the width of the lower slot 142, and the bottom of the second table 16 forms a slot surface 161 of the slot 14.
[0039] Correspondingly, the plug cover fixing member 3 includes an upper insert block 31 corresponding to the upper slot 141 and a lower insert block 32 corresponding to the lower slot 142. The lower insert block 142 rests on the groove surface 161. The upper insert block 31 includes an upper tail portion 311 flush with the peripheral wall of the first table 15, and the lower insert block 32 includes a lower tail portion 321 flush with the peripheral wall of the second table 16. The width of the upper slot 141 is smaller than the width of the lower slot 142, which facilitates vertically securing the plug cover fixing member 3 between the upper slot 141 and the groove surface 161, thereby preventing the plug cover fixing member 3 from being dislodged. Furthermore, the upper tail portion 311 is flush with the peripheral wall of the first table 15, and the lower tail portion 321 is flush with the peripheral wall of the second table 16, thereby ensuring a tighter fit between the plug cover fixing member 3 and the tail cover body 1, thereby preventing the plug cover fixing member 3 from being dislodged from the tail cover body 1.
[0040] As an improvement to the positioning of the plug cap fixing member 3, the outer edge of the first platform 15 protrudes beyond the outer edge of the second platform 16, forming a step between the first platform 15 and the second platform 16. This step is used to support the electric toothbrush housing. When the electric toothbrush housing is placed on the step, since it fits around the outer periphery of the second platform 16, it prevents the plug cap fixing member 3 from radially separating from the tail cap body 1. This makes the assembly structure of the electric toothbrush tail plug structure of this embodiment of the utility model more stable.
[0041] Furthermore, the tail portion includes a tail body 21, the clamping block 22 is formed at the lower end of the tail body 21, and a gap is formed between the plug cover fixing member 3 and the tail cover body 1 for accommodating the tail body 21. In this embodiment, the cross-sectional shape of the gap is the same as that of the tail body 21, which can effectively prevent the clamping block 22 from falling out of the gap.
[0042] Furthermore, the tail cover body 1 includes a concave surface 17 for placing the USB plug cover 2, and the concave surface 17 is located in the middle position of the height direction of the second table 16. The tail cover body 1 is formed with a stopper 18 at the cavity 13 corresponding to the insertion direction of the lower plug block 142, and the lower plug block of the plug cover fixing member 3 is provided with a notch 33 at the corresponding position of the stopper 18. Figure 4It can be seen that when the concave surface 17 and the bottom of the second table 16 are staggered, the USB plug cover 2 is not only subjected to the friction on both sides during the pulling process, but also to the oblique pressure formed between the concave surface 17 and the bottom of the second table 16, which improves the assembly stability of the USB plug cover 2. At the same time, please refer to Figure 6 and Figure 8 As shown, the tail cover body with the stopper 18 and the plug cover fixing member 3 with the notch 33 also increase the assembly stability of the electric toothbrush tail plug structure of the embodiment of the utility model to a certain extent.
[0043] The embodiment of the utility model adds a plug cover fixing piece and fixes it on the tail cover body through an installation structure. The installation structure can be a plug-in structure, so that the USB plug cover of the embodiment of the utility model does not need to adopt a mushroom head structure, and the tail cover body does not need to be provided with an anti-drop hole. The assembly operation of the tail plug structure can be completed by manual operation without the need for additional jigs or the arrangement of additional workstations, which greatly improves production efficiency and saves production costs and labor costs.
